cartechboy writes "It looks like the old-school windshield wiper is about to be replaced by new technology — but not until 2015. British car-maker McLaren is apparently developing a new window cleaning system that is modeled from fighter jet tech. The company isn't revealing exactly how it will work, but the idea comes from the chief designer simply asking a military source why you don't see wipers on jets as they land. Experts expect McClaren to use constantly active, high-frequency sound waves outside the range of human hearing that will effectively create a force field across a car's windshield to repel water, ice insects and other debris. Similar sound waves are used by dentists to remove plaque from teeth. Windshield wipers were originally invented by Mary Anderson, who received a patent in 1903. She envisioned the design after seeing drivers open the windows of their cars in order to see out of them in the rain, solving the problem with a simple swinging arm device with a rubber blade."
